WALL-corms.

Application filed February 13; 1915. Serial No. 8,065.

The primary object of this invention is to provide an improved Wall coping that will shed all of the rain that falls on the surface thereof in one direction.

Another object is to provide means in a wall coping whereby each coping will be alined properly with its adjacent coping.

A further obj ect is to provide a Wall cop ing with weakened lines so that said coping can be easlly sectloned so as to provlde a proper fit indeslred places.

A still further object is to provide the overlapping portion of a wall coping of such improved design whereby the mortar which is used for adhering the co pmgs to each other will not fall from between'the copings after it is dried.

Other and further objects Wlll appear 1n the specification, and be specifically pointed out in the appended claim, reference being had to the accompanying drawings exemphtying the invention, and in which,

Figure 1 1s a perspective vlew showing this improved type of wall coping mounted on a fire wall. j j j j Fig. 2 is a section taken on the line II-II, Fig. 1.

Fig. 3 is an inverted view of this'improved wall coping, the central portion thereof be ing broken away.

Fig. 41 is a section' taken onthe-line IV-IV, Fig. 2.

Fig. 5 is a section taken on the line V-V, Fig. 2.

Fig. 6 is an end view on a reduced scale, showing this improved wall coping extending over an. extremely wide wall.

Fig. 7 is an end view, on a reduced scale, of a pair of meeting fire walls provided with single deck wall coping, the lower coping adapted to receive the drip from the front edge of the upper coping.

Fig. 8 is an inverted view of one of the copings shown in Fig. 7.

Referring to the drawings, and more particularly to Fi s. 1 to 5; 1 designates a fire wall, showing t is improved coping mounted thereon, each coping being designated as 2. Said coping has an upper inclined deck 3,

and the lower inclined deck 4, said decks being inclined in one direction, and being joined by a step-down portion 51 Depending from the front edge of the'deck 3 is a ver tically arranged drip6, and depending from the rear end of the deck 4 is avertically ar ranged drip'7. Formed on the front end of the deck 3, and at the highest point thereof is an ipturned portion 8. Extending along one side of the decks 3 and't and step-down portion 5 is an'overlapping portion 9.

Formed" on the side of the coping 2 opposite to the overlapping portion is arib 10. EX

tending from oneiside of said coping adjacent the rib 10 and the drip portion 6 is an abutting portion-11. f

In mou'ntingthis improved copingon a fire wall, it'is preferable to lay an outer single row of'brick 12 on top of the wall. Each copingis laid with the overlapping portion 9 to theright of the workman on the bed of mortar Wheneachsucceeding coping is laid, theoverlapping portion9 of each cop- I ingwill'overlap the rib 10 of the adjacent coping, mortar, of course, being first applied to the rib 10. The 'o'verlapplngportion 9 ofeach coping hasfan inclined under face 14, sa d face being lncllned downwardly toward the adjacent coping. This construction is very valuable retaining the mortar between the overlapping portion 90f one coping and therib 10 01% the adjacent coping, especially after the mortar has become dried, as it is very often the mortar, after being dried, becomes loosened, and the elements drive the mortar out from between the overlapping portion. With this improved construction of overlapping portion, the mortar will assume the formation of a wedge and thereby cannot fall away.

With this improvedform of coping, when the first. coping is laid properly, the abutting portion llwill abut against; the front fac of thefire wall, and when the next coping is laid, the inner face 15 of the drip portion 6 will engage against said abutting portion thereby assuring the last laid coping of being laid in alinement with the preceding coping. This abutting portion 11 will also prove valuable as a mortar-back, as shown more clearly at 16 in Fig. 4-, for, when the mortar is applied. between the copings, the

mortar cannot fall through on account of be ing backed against the abutting portions 11.

In. mounting coping on a wall, it is sometimes necessary to section one of the copings in order to make a proper fit. Iiiord'ento provide improved means for so doing, grooves 17 are formed "transversely or-this improved coping, forming weakened lines, said grooves extending across the outef'sur face of the coping, forming sections 18. When iUis desired-t6 sectiini a coping; the

elected groove is followedtwitha cl 1i sel,-- and the outer harder surface of the groove is logoken, {sai operation -bei'ng'fol-l0wednp p ing t ec i apa t- 'turnedf po ition, 8;- .which--is formed on the 3 highest point of the inclineddeckfig For, even though the; rain fall at; a difivin'go angle against thelinclineqf the dckfipthe;portion 8 williserve as. a "Waterbackl and? will turn the water in direction] toward the roof; n wi lj a low he; as to ru efii h inclined "surface to the-drip;PQ 1-,ion6,' thereby removing alrdangr for; Qtheidirty water frond co ning contaftwith; the front face f li a a a Injniakingf thisimproved co ingiit is preferable to have itof suchfa wi v th that the drip portion 7 will exte'nd'a considerablejdisam f omt ner fac off e r ll o that the "drip" will take place; beyond; the nt ther-strip arhereby ii giay with leaky 1 more, which ery; oftenpeeur djaenwheient rip n u it'f fT K watri"" tfingb w h a n the eeling- Q a a i This improved; coping j is' also preferably e lst'ruete -wi ht w c ne e s, nd. ore especially when an extremely Widj wall, as shown at 21 in is tdbecoped, as it is desijred'to getfthe" r away'from he 11 ps 'fi a ff'th' in?

The construction of coping shown in Figs. 7 and'8 has the same principle embodied as relates -to' tlie copiiig 2 with the exception that this coping has but one inclined deck 25 andca-n be used on a Wall that has a horizontaltop surface and has not a topping of single rowbrick, as shown in Figs. 1 and 2. Saidcopingi25has a resting strip 26 which is adapted to engage the top of the fire wall 27 in lieu of the single row of brick 12 that is used'relative to the copin 2.

As shown iir Fig.4 7; the lire wall 27 extendsupwarjdly beyond the fire wall 28, said Walls abutting.- This illustration shows how the front-drip portion 29 of the coping 25 overhangs thecopingr30 of the fire wall 28, saidcoping30adapted to receive the drip fr orn the dripjportion. 29 of the coping 25. In;. th1sinstance, the upturned portion 31 of the coping 30 will prevent the drip from the front portion. of the coping 25 from gaining aecessgbetween the. fire walls 27 and 28.

When tlie ordinary type of coping is used on, adjoining walls, after two'or three days continuous rain; the walls get so water soaked from three to five feet down, that numerous complaints occur from the upper floor tenants ofsuch buildings, and generally-the interior. decorations are ruined and tlie.exte1'ior walls are discolored from accumulated soot and "dirtl' This improved Wall coping is principally tobeused'on such'walls' as factory buildings, warehouses, adjoining buildings when t vo'wallsl come together,'on side and rear w'alls'of tenements-and apartments and is adaptedtoreplace the old style coping which sheds'wateron both sides.

What I clainiis:

Ajwall coping comprising'an upper deck and a lower deck, a step down portion adjoiningrsaid decks, said decks inclining in the safnedirection, an upturned portion extending, alongthe upper end of said upper deck, a'vertically formed front wall leading to the top of'said upturned portion, said vertically formed front wallterniinating at the highest 'poi'ntof the top surface of said p u ne por on,
